"While the national average didn’t fall quite as far as anticipated for Memorial Day, it was still one of the most affordable since 2021— and, when adjusted for inflation, among the cheapest in nearly a decade," said Patrick De Haan, head of petroleum analysis at GasBuddy. "As we move into the heart of summer, I believe we’re likely to see a relatively stable stretch for gas prices as refinery maintenance wraps up. Don’t expect the national average to rise above $3.30 per gallon, nor drop much below $3 for now. While refining issues on the West Coast are beginning to ease, several factors could still influence prices in the weeks ahead—including growing uncertainty around the upcoming hurricane season."
